A)atented Feb. 8, 1910.

Application filed April 13, 1908. Serial No. 426,675.

To all 'whom it may concern:

Be it known that we, JAco L. McKEn and ROBERT R. GATES, citizens of the United States, residing at Dunlap, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Door-Openers; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a device for operating doors the same being partially automatic in that upon manually operating a certain lever mechanism the door will be opened or closed.

To the end that the invention may be understood the accompanying drawing has been provided in which,

Figure 1 is an elevation of a door framing with part of the casing removed to show the operating mechanism, the door being shown standing open. Fig. 2 shows a portion of the same but with the door closed and the mechanism thrown to a position opposite from that shown in Fig. 1. Fig. 3 is a horizontal section of some of the parts as viewed in Fig. 1 taken on line a2 of the latter ligure. Fig. l is also a horizontal section on line 'y 3/ Fig. 1 showing the door in its closed position. Fig. 5 is a vertical section of the door jamb and mechanism for engaging and shifting the bolt-latch of the door. Fig. G-

is an elevation of the bifurcated end of a rod provided with a roller and used in connection with the door operating parts. Fig. 7 is a horizontal section of a latch operating mechanism shown in Figs. 1 and 2.

The mechanism about to be described is provided in order that a person may readily open the door by means of his foot when his hands cannot be used for the purpose as, for instance, when carrying a load, said mechanism being so arranged that after having passed out the door may be closed in the sam-e way.

The letter A indicates the door and B the door frame.

C indicates the easing or 'finishing' above he door, that at the right hand side of the door shown in Figs. 3 and 4c by the letter D having been removed in Figs. 1 and 2 so as to show the operating mechanism.

Secured in any convenient manner to some part of the framing sov as to be concealed from view, is a plate E provided with a stud F, Fig. 4, on which is pivotally carried, as at G, a lever l-l adapted to rock in a vertical plane. This lever has a slot below its pivot as at J which extends in a general direction substantially at right angles to the portion of said lever above the pivot, each end of said slot being preferably enlarged as indicated by K. Said lever above its pivot is also provided with an arm L at one side from which a rod M is suspended, the latter carrying a bar N having a slot O therein the purpose of which will be described presentl-y.

lVitliin the slot J of the lever H is one end of a rod P provided with a friction roller Q, Fig. 6, the lower end of said rod being suitably attached to a lever R near the floor, Figs. 1 and 3. This said lever is provided with trunnions R which extend through suitable bearings S let into the casing D at each side of the wall, each trunnion carrying a foot-lever T. Above the lever R and secured to the framing B is a bracket U through which extends a vertically adjustable member V; adjustment thereof being had by means of a suitable nut lV. To this member is attached one end of a spring Q whose lower end is suitably connected to the said lever R and normally holds the latter in a raised position. The upper eX- tremity of the lever H is bifurcated as shown in Fig. et and between its extremities lies the end of a horizontally disposed rod 3, slotted at a, which extends through an opening 4L in the door jamb, its opposite end being pivotally attached to the short arm 5 of a lever, Fig. 3, which is on a stud 7 suitably secured to the underside of the door framing.

Secured to one side of the door near its I top is a slotted bar 8 with which. a long arm of the lever 9 engages, said arm being forked as shown at 10 in Fig. 1 and provided with a roller (not shown) similar to Q carried by t-he rod P in Fig. G. On the door frame or jamb B is the usual keeper 11 for receiving and holdingV the latch-bolt 12 of the door, a portion of this being shown in Fig. 5 entered through said keeper, there being a. hole entirely through the easing at 13 in the ligure lastnamed, into which extends a sliding bolt 14 guided in a casting 15 in a horizontally disposed slot 16, said bolt being provided with a pin 17, Fig. 7, which extends into the slot O of the member N A hereinbefore described. Said member N is adapted to shift vertically within the casting 15 in the slot 18, Fig. 7. The said slot O as may be seen is so disposed with reference to the sliding bolt 14 that as the member N is raised or lowered the said bolt is shifted .in the direction of its length but this action will be better understood in the description of the operation.

In Fig. 2 the door is shown closed with the lever H vin the position it occupies at that time. The lifting tendency of the spring i2 will, however, raise the rod 2 so as to carry it to the highest end of the slot as shown by broken lilies in that figure, ready for the next movement. If pressure be exerted upon one of the levers T the lever H will be thrown to the position shown in Fig. 1 with the result that the door will be thrown to the open position. It will be noted in Fig. 4L that a push on the rod 3 in the direction of the arrow will move the arm 5 and swing the lever 9 on its pivot with the result that the long arm of this member will push the door open to the position shown in Fig. 3. The lever H having reached the position shown in Fig. 1, t-he upper end of the rod P by reason of the pull of the spring will move into the upper part of the slot ready for the closing movement. If pressure be again exerted on one of the levers 'l the short arm 5 of the lever S) (Fig. 3) will be pulled causing t-he long arm to move to the position shown in Fig. 4t and in doingso will pull the door shut, the end of said long arm sliding along the slotted bar 8 in either movement of said door.

Provision must be made for disengaging the latch-bolt of the door from the keeper 11 when the door is to be opened, and this is accomplished through the sliding bolt lat. ln Fig. the member N is in its raised position or the position it occupies when the door is closed with said bolt 111 withdrawn from contact with the said latch-bolt. As the lever H moves from the position shown in Fig. 2 toward the position shown in Fig. 1 the first action is to depress this member N. The slanting portion of the slot O shifts the bolt 14E toward and against the latch-bolt by means of the pin 17 forming said latchbolt out of its keeper 11. However, as the door moves to the closed position the member N rises to retract the bolt l-t so that when the latch-bolt 19J reaches its keeper the said bolt 14 is out of the way to permit the door to properly latch. It is designed that tht` member N cause the latch-bolt 12 to be forced out of the keeper before any opening seen that the door can be operated from either approach and can be readily closed after passing through the opening.

By means of the nut lV and the hook V the spring Q may be adjusted to produce the necessary tension and this maybe done by removing the casing which conceals it or b v providing means that can be operated from the outside to accomplish the same purpose without the necessity of the removal of the casing.

lVe have not gone into the detail as to the manner of securing the various parts in place since any means can be used for so doing. Such alterations or changes in our device can be made as may be found of adv vantage without departing from the spirit. and intent of the invention.
